摘　　要：针对标准鲸鱼优化算法(WOA)易早熟的缺点,提出一种改进的鲸鱼算法。设计一种基于指数函数的收敛因子以协调WOA算法的探索与开发能力,提出基于旋转操作的精英学习算法来提高算法的局部寻优能力,并采用自适应变异操作以减少算法陷入局部最优的概率。通过10个标准测试函数验证改进的鲸鱼算法IWOA的有效性。研究结果表明:IWOA具有收敛速度快、全局寻优能力强的优点;将IWOA算法应用于钢铁烧结的配料过程,有效降低了配料过程的成本。Aiming at the shortcomings of standard whale optimization algorithm(WOA),an improved whale algorithm was proposed.An updating formula of convergence factor based on exponential function was designed to coordinate the abilities of exploration and exploitation.In order to improve the local searching ability of the algorithm,an optimal learning strategy based on a rotation operation was proposed for elite individual,which strengthened the local searching ability of the algorithm.Adaptive mutation operation was adopted to reduce the probability that the algorithm falled into the local optimum.Simulation experiments were conducted on the 10 test functions.The simulation results show that the improved whale optimation algroithm(IWOA)has better performance in convergence rate and global optimization ability than other comparison methods.The algorithm is applied in the blending process in the sintering process of iron and steel,which effectively reduces the cost of the blending process.
